Green Convergence (GC) and First Philippine Holdings (FPH), through its Ako Ang Bukas (AAB) Advocacy Program, held a greenhouse gas (GHG) accounting workshop for businesses and civil society organizations (CSOs) on October 16, 2025, at Discovery Suites in Ortigas Center, Pasig City.
The workshop was co-organized with the environmental technical working group of the Sustainability Development Goals (SDG) Stakeholder Chamber of the Department of Economy, Planning and Development (DEPDev).
Jonas Dumdum of the environmental technical working group of DEPDev’s SDG Stakeholder Chamber echoed the sole purpose of the workshop, “you cannot report what you cannot measure, and you cannot measure if you do not identify,” linking it with how international reports still show that the Philippines is still number one in disaster risk-related issues.
Dr. Angelina Galang, Program Director of AAB and Founding Trustee of GC, kickstarted the workshop with a discussion of the ecological paradigm, anchored on the seven environmental principles: (1) Nature knows best, (2) All forms of life are important, (3) Everything is connected to everything else, (4) Everything changes, (5) Ours is a finite Earth, (6) Everything must go somewhere, and (7) Nature is beautiful and we are the stewards of God’s creation.
“We have disturbed, if not destroyed completely, the natural world. We have strayed further and further from nature to the extent that it imperils its ability to sustain our quality of life,” Dr. Galang emphasized the need to revert to nature through the principles, adding that it is the qualitative framework needed to understand the need for GHG accounting.
Agnes de Jesus, Chief Sustainability Officer of FPH and Business Task Force Head of AAB, then delved deeper into GHG accounting and its significant contribution to addressing climate change impacts.
De Jesus highlighted the Philippines’ commitment to reducing emissions under the Paris Agreement and introduced the AAB household GHG calculator web app as a practical tool to help households understand and track their carbon footprint.
She emphasized that ‘the choices we make will affect the climate,’ altogether suggesting to consume less power, consume less processed food, eat local and organic, minimize packaging, and shorten and plan travel routes through lifestyle change and tree planting.
On entity-level GHG accounting, de Jesus reviewed the boundaries and data needed to calculate for entities’ carbon footprint—scope 1 summed up as “burning fuel in your facility,” scope 2 or “buying power and steam” outside your facility, and scope 3 means “outside Scope 1 and 2”—and introduced the features of the AAB entity-level GHG calculator.
In line with the awareness of their carbon footprint through the calculator, she also introduced the mitigation hierarchy to guide decarbonization efforts—avoidance, minimization, reduction, and removing, and nature-based or man-made offsetting as last resort.
Milagros Serrana, Program Leader of AAB, led the workshop-proper on the use of the AAB household and entity-level GHG calculators. She demonstrated how to input data and how the calculator presents graphically the results which show the users’ hotspots.
Several participants were then able to share their results and reflections from the GHG calculation workshop.
Virgen Milagrosa University Foundation used their own data to try out the AAB entity-level GHG calculator and said that it was helpful for them to formulate action points for their university.
Airspeed International Corporation shared that knowing their emission hotspots through the calculator helped them validate their roadmap to promote and advocate sustainable framework up to year 2030.
DEPDev shared that the calculator was interactive and user-friendly.
Ako Ang Bukas (or “I am the future”) is a movement with a central campaign, “Quantum Leap NOW: Climate Neutrality 2050.” It seeks to involve all sectors and levels of society nationwide in taking urgent, concerted action to address the climate crisis facing the country and the world.
